iPhone 16 Pro battery spotted online with metal shell, may offer better heat dissipation

The iPhone 16 Pro is expected to arrive in 2024 as the successor to the iPhone 15 Pro launched in September, and details of Apple’s next flagship smartphone have already started to surface online. According to details shared by tipster Kosutami (@KosutamiSan) on These improvements are also expected to make their way to the iPhone 16 Pro Max.

The tipster leaked four images of an alleged prototype of the iPhone 16 Pro battery from different angles. While this “early stage” prototype of the component is L-shaped – like Apple’s existing iPhone batteries – it is not covered in foil and has a metal shell. The tipster has also shared close-up images of the component, which shows that it is a lithium-ion battery, suggesting some of its specifications.

The images suggest that the iPhone 16 Pro may be equipped with a 3,355mAh battery, which means that its capacity will be slightly higher than its predecessor, which has a 3,274mAh battery. Apple doesn’t disclose exact iPhone battery capacities, but these details are usually revealed in teardown videos after new iPhones are launched. The leaked battery capacity increase makes sense, as the iPhone 16 Pro is likely to have a slightly larger 6.3-inch display – which would provide room for a larger battery.

The tipster claims that the iPhone 16 Pro’s battery will be housed in a frosted metal shell – earlier prototypes were said to have a glossy finish. The inclusion of a metal shell suggests that the iPhone 16 Pro will offer better thermal management than its predecessors, as a metal shell can provide better heat dissipation than the existing solution.

Apple’s iPhone 15 Pro and iPhone 15 Pro Max were both affected by an overheating issue that was previously thought to be related to the new A17 Pro chip, until the company released software fixes to resolve the issue.

However, changes to the battery design are expected to lead to better thermal management on the iPhone 16 Pro at the hardware level, meaning they can run cooler than their predecessors. These benefits are also expected to be available on the larger iPhone 16 Pro Max model, as it may feature a larger version of the same battery technology.
